can you please help me with this

[Michael Sherman (msherman-uchicago)]

I'm pretty sure this is caused by this recent docker-py error from a new version of the requests module.

https://github.com/docker/docker-py/issues/3256

I was able to workaround it by manually installing requests==2.31 into Kolla's virtualenv on the target host.

More generally, the workaround can be added to `docker_sdk_pip_packages` for the docker_sdk role in the Kolla Ansible collection.

```
docker_sdk_pip_packages:
  - "docker>=3.0.0,<7.0.0"
  - "requests<2.32" # workaround for https://github.com/docker/docker-py/issues/3256
```

[Siddalingeshwar (siddu2tg19cs045)]

Can you please help me out regarding how and where to locate these "docker_sdk_pip_packages". So that I can modify the "request" version to check the work around.

[Maksim Petyakin (petru4o)]

Hi, I did this:
pip list | grep '(docker|requests)' (view installed packages)
pip uninstall requests, Delete and reinstall pip install requests==2.31.0
it helped me, thanks Michael Sherman for the hint

[Travis Best (tb2097)]

To give a little more detail here...
for whatever user you did the initial install to, you need to modify the ansible_collection config file to put the exception in, so it is using the correct version (2.31.0) in the venv on the target machines.

To do this I needed to sudo su - then navigate to

/home/<deployment user>/.ansible/collections/ansible_collections/openstack/kolla/roles/docker_sdk/defaults

vi main.yml

```
docker_sdk_pip_packages:
  - "docker>=3.0.0,<7.0.0"
  - "requests<2.32" # workaround for https://github.com/docker/docker-py/issues/3256
```

[Deepak (deepakkanda)]

Hi,
I had a similar issue but requests less 2.32 still fails on two specific nodes. anyone have thoughts?
